The reading talks about three theories which cause for extinction of Steller's sea cow which cast doubt by the lecturer.
Firstly, the believe that this extinction caused by over haunted from Serbian people, but the lecturer said that these marine animals was too big almost nine meters and ten tons, in addition the population of Serbian was not too big, so they do not need to haunt a lot.
Secondly, the reading stated that the decline in food cause extinction in this animal, while the professor said that there was not shortest of food on that area. If there was shortest of food there, other animals would die too like whales, but whales did not decline on that area.
Thirdly, some people believe that European fur traders was the main cause of extinction of this animal because they caught the last sea cow in 1768. Another, reason is that they had good weapons which could kill them rapidly, however the speaker said that it might seem that the cause of extinction was traders, but these animals decline long time before Europeans arrived there.
In conclusion, the lecturer denies the theories which mentioned in the reading about extinction of sea cows by giving some reasons.
